Hi Jim,

Sadly your idea doesn't work in C++, because C++ has member functions.  That is, we can write things like this:

struct Widget {
    void reset();  // reset the widget
};
[...]
std::unique_ptr<Widget> p = std::make_unique<Widget>();
p->reset();  // reset the pointed-to widget by calling Widget::reset() member function
p.reset();  // reset the pointer's own value to nullptr


But, isn't the .reset() implemented on the unique_ptr<> template as a operator. override?  which takes precedence over the default behavior...

No, C++ doesn't permit overloading the "." operator at all.
It's just that `p.reset()` calls `unique_ptr<Widget>::reset`,
and `p->reset()` calls `unique_ptr<Widget>::operator->` followed by `Widget::reset`.

I think you'll have to learn more about how C++ currently works, before working on proposals to change it.
